Biologically Active Filtration Media Properties: Practical and Mechanistic Implications
(University of Waterloo, 2017-01-16)Biologically active filtration [BAF] can be used to concurrently remove particles and natural organic matter during drinking water treatment. The selection of a given media type for use in BAF can impact filter performance, ... -
Contemporary Forest Harvesting Impacts on Drinking Water Quality and Treatability
(University of Waterloo, 2019-10-31)Forested watersheds supply ~75% of global accessible freshwater resources and serve as important sources of drinking water. Both natural and anthropogenic landscape disturbances in these regions can deteriorate water quality ... -
Dissolved organic carbon production and transport in a constructed watershed in the Athabasca Oil Sands Region, Alberta
(University of Waterloo, 2018-01-23)Within the Western Boreal Plains, a significant amount of surface cover has been removed through open-pit oil sands mining activities, which includes fen peatlands. Fen construction has been performed on the post-oil sands ... -
Dissolved Organic Matter in the Anthropogenically Impacted Grand River and Natural Burnt River Watersheds
(University of Waterloo, 2012-01-03)Dissolved organic carbon (DOM) is one of the largest cycled organic carbon pools on Earth and an important biogeochemical factor in aquatic systems. DOM can act as an energy source for microorganisms, alter the depth of ... -
The Effect of Selected Coagulants on Chloride-to-Sulfate Mass Ratio for Lead Control and on Organics Removal in Two Source Waters
(University of Waterloo, 2009-01-22)Lead is a known toxin, with the ability to accumulate in the human body from as early as fetal development. Lead exposure is known to cause a myriad of health effects which are more prominent among children. Health effects ... -
Plankton Metabolic Balance and its Controlling Factors in the Coastal Zone of the Laurentian Great Lakes
(University of Waterloo, 2007-10-01)Plankton metabolic balance (PMBm) of the surface mixed layer was calculated as the ratio of areal rates of gross photosynthesis (AGP) to community respiration (AR), and estimated for four Laurentian Great Lakes coastal ... -
Predicting the Effect of Catalyst Axial Active Site Distributions on a Diesel Oxidation Catalyst Performance
(University of Waterloo, 2012-08-30)Zone-coated diesel oxidation catalysts (DOCs) can be used to obtain overall improved performance in oxidation reaction extents. However, why this occurs and under what conditions an impact is expected are unknown. In order ... -
Salinity Effects on Dissolved Organic Carbon Concentration and Quality in a Constructed Fen Peatland, Fort McMurray, AB
(University of Waterloo, 2020-08-05)In northern Alberta, oil sands mining disturbs the landscape; reclamation to an “equivalent land capability” is required, and industry is testing peatland construction as part of landscape reclamation. To determine if these ...
